Our Business Is the Truth


In 2004 Dr. Laken founded Cephos on the basic principle of getting to the truth. In 2004, Cephos funded the largest brain imaging lie-detection study to date. In this study, collaborators at the Medical University of South Carolina and Cephos scientists showed that specific algorithms could be developed that automatically detected deception in the human brain. The study was of such scientific importance that the results were published as a Priority Communication in the journal of Biological Psychiatry – reserved for 1% of the publications. There are now over 30 publications, from 17 different groups, from Harvard, Germany, Australia, Japan, University of Hong Kong, Georgetown, University of Chicago, University of Sheffield, Wallace-Kettering Neuroscience Institute, Temple and the University of Pennsylvania. Because of the importance this has to the judicial system, the MacArthur Foundation has contributed over $10M in funding. Initial results from this work published in the Proceedings of the National Academies of Sciences supported earlier publications.


Cephos is the world-class leader in providing fMRI lie detection, and in bringing fMRI technology to commercialization. Scans have been performed on people from across the world who have reported wrongful convictions, employment disputes, wrongful terminations, and accusations of sexual/harassment orpedophilia.


Our successes include the following advances first made by Cephos:


  • Cephos has published the largest fMRI studies and has been asked to present to the National Academies Committee on Science, Technology and Law, Stanford Law School, Sandra Day O’Connor Federal Courthouse, the National Judicial College, Association of American Law Schools, Siemens Customer Education Symposium, Akron Ohio Law School, and to the Neuroethics Society.
  • Cephos has documented over 97% accuracy in blind clinical testing, analyzing data from more than 250 people and more than 300 scans.
  • Cephos is the only company licensed to perform brain-based lie detection.
  • Cephos has the only exclusively owned, issued fMRI patent in this field. Cephos has been granted patent 7,565,193 in the U.S. and has also applied for numerous patents worldwide. In addition to these applications, Cephos holds an exclusive license to intellectual property developed at the Medical University of South Carolina (USPTO 20060036152 and 20050119547). In the U.S., Cephos is represented by one of the top ten intellectual property law firms, WilmerHale.

After offering our advanced brain imaging services, lawyers requested help reviewing DNA evidence and aid investigating civil and criminal. In 2008, Cephos expanded our commercial offerings to include DNA evidence work as well as private investigations. Cephos investigations span from a few hours of routine service to multimillion-dollar litigation. Investigators are trained, licensed and bonded. Cephos forensic DNA services are overseen by Dr. Laken. He is a qualified expert and has worked on cases that range from rape to murder. Cephos is a proud provider to the Public Defender’s Office in Massachusetts.

Management Profiles



  Curriculum Vitae

Steven Laken, Ph.D., President & CEO

According to Hopkins Medical News, at the age of 26, Steve Laken "had already achieved more public acclaim than many scientists receive in a lifetime." He had been featured on the nightly news of all four major television networks, in The New York Times, Baltimore Sun, USA Today and on National Public Radio and the Associated Press Radio Network. In his fourth year of a graduate program in cellular and molecular medicine, Dr. Laken was part of the team credited with discovering the first familial genetic mutation that causes colorectal cancer, and with developing a simple blood test to identify it. The American Cancer Society and the American Society of Clinical Oncologists now recommend genetic testing based on this work.


Subsequent to graduate school, Dr. Laken worked at Exact Sciences Inc. as Director of Business Development and Intellectual Asset Management. He managed the firm's portfolio of intellectual property, licensed new technology and genes, established collaborative relationships with scientists and industry, and designed and managed clinical studies. He successfully identified the firm's first product and implemented its launch, establishing commercial operations two years ahead of the initial goal. He played a key role in raising Series D financing and was part of the management team that took Exact Sciences public through an Initial Public Offering (IPO).


Dr. Laken is a recipient of the MIT Technology Review 100 Young Innovators Award (2002) and the David Israel Macht Prize from Johns Hopkins University (1999). He holds four patents and was instrumental in developing four commercially available DNA-based diagnostic products both at Johns Hopkins and at Exact Sciences. He holds a B.S. in Genetics and Cell Biology from the University of Minnesota and a Ph.D. in Cellular and Molecular Medicine from the Johns Hopkins School of Medicine. He has testified as an fMRI Expert and as a DNA forensic expert.


Benjamin McDonald, Cephos Lead Investigator

Mr. McDonald served in law enforcement and security for 24 years as a Patrol Supervisor, Watch Commander, Prosecutor, Director of Training, Academy Drill Instructor, Physical Skills, Investigator, Firearms Instructor, and State/Federal Law Enforcement Leader in Training. He also served several years in the Department of Justice as an Academy Director for the Office of Police Corps and Law Enforcement Education.


Mr. McDonald successfully employed his practices in local, municipal, state and federal organizations and has conducted numerous municipal and private sector investigations. He is an accomplished educator and investigator committed to helping clients with their complex litigation needs.


Mr. McDonald is also a successful entrepreneur and has extensive experience in the private investigative industry. He is an active and respected member in numerous professional societies, and he devotes some of his time to pro bono casework. His project management expertise and his many years of experience have made him a leader in training and investigations.

Frank Kozel, M.D., M.S.C.R.

Dr. Frank A. "Andy" Kozel has been instrumental in the development of fMRI to detect deception. Dr. Kozel is the principal investigator on scientific studies that began in 1999 which demonstrated the ability to distinguish truth from deception using fMRI. Dr. Kozel graduated cum laude from Yale University in 1989 and completed his M.D. degree from the University of Virginia in 1993. Due to a military obligation, Dr. Kozel completed his internship at Wilford Hall Medical Center, Lackland AFB, Texas. He served as a flight surgeon at Dyess AFB, Texas and Maxwell AFB, Alabama. Dr. Kozel then moved to the Medical University of South Carolina where he completed a Psychiatric Residency, a Neuroimaging and Brain Stimulation Fellowship, a Masters of Science in Clinical Research, a Veteran's Administration Special Fellowship in Psychiatric Research/Neuroscience at the Ralph H. Johnson Veteran's Administration Medical Center, and stayed on as an Assistant Professor in Psychiatry. Dr. Kozel moved to the University of Texas Southwestern Medical Center in July 2005 where he is an Assistant Professor in the Department of Psychiatry. The current focus of his work is functional MRI (fMRI) detection of deception as well as brain stimulation and neuroimaging projects related to mood regulation.
